Decades of underinvestment has left tens of thousands of schools across the country with inadequate ventilation systems, a problem that is now front and center in the debate to reopen schools during the pandemic.Nationally, 90 percent of schools fail to meet minimum ventilation standards. It’s an issue Dr. Joseph Allen has been sounding the alarm about since COVID-19 first shut down schools earlier this year.“We’ve chronically underinvested in our schools’ buildings,” said Dr. Allen who serves as the director of the Healthy Buildings program at the Harvard Chan School of Public Health.Dr. Allen and his colleagues have spent months analyzing school buildings, and back in June, they released a detailed 60-page report that school districts could follow in order to safely bring kids back into the classroom.In order to keep COVID-19 from spreading in schools, two things have to happen: everyone in the buildings must be wearing masks and school districts need to ensure buildings have proper ventilation, the report found.“If air is being recirculated and not filtered, all of that air that’s coming from one space and going to another could be potentially contaminated and spread the virus,” Dr. Allen said.But replacing decades-old ventilation systems that may not work properly is expensive and time-consuming. Because of that, Dr. Allen is recommending school districts also consider portable air cleaners for classrooms.Through his research, Dr. Allen found that if you can change the air in a classroom five times per hour, it cleans the air in that space every 12 minutes. However, the air cleaners must be equipped with a HEPPA filter in order to be effective.Even something as simple as opening windows could reduce the transmission of the virus.“If you look at the cases of spread in school right now, they all share common traits; it’s no mask-wearing and low to no ventilation. When we do that, we can guarantee there will be more cases,” he explained.Last week, the Healthy Buildings program also released a detailed portable air cleaner calculator. The tool allows school administrators to input the size of the classroom, even ceiling height, and then determine the kind of air cleaner that would most effectively keep COVID-19 from spreading.“It is critically important that we get kids back into in-person learning and we haven’t treated it as this national priority that it needs to be,” Dr. Allen added. 2438

DENVER, Colo. — It's no secret, rent in Colorado isn't cheap. Many people seek out a roommate just to cover the cost of living. However, sometimes roommates have major disagreements. One major point of contention often involves the use of marijuana in the home."If I want to smoke a lot of weed I don’t think that’s an issue," said Damion Green.Finding roommates with his mentality hasn't been easy for Green."I’ve been through hell with people. People who insist you smoke outside, people that freak out about paraphernalia sitting around," Green says of his issues with prior roommates.That's why Angeliki Gousetis created 420 Friendly Apartments — a Facebook group connecting fellow marijuana smokers who are looking for roommates with similar interests.The group doesn't find a place to rent. Dan Garfield, an attorney who specializes in cannabis law, says "it’s just as difficult to find a weed-friendly landlord as it is to find a tobacco-friendly landlord." And if you do find one, Garfield says, Be prepared to pay a larger security deposit.""There’s no worry that I’m a professional and because I’m in finance, I can’t be 420-friendly, so if, God forbid, somebody sees me, I have to hide myself. There’s no hiding. Just be yourself," said Gousetis, a New York realtor.She started the same group in New York before creating one in Denver over the summer. More than 3,000 people have already joined, including Green, who posted to the group he was in need of a place to live. He says within a matter of days, he found his new roommates.Gousetis says she's helped connect people in 25 states. She calls them bud-mates. The group is free to use. Because of the early popularity, Gousetis created two more groups in Boulder and Colorado Springs.This story was first reported by Gary Brode at KMGH in Denver, Colorado. 1829

Debate moderator Chris Wallace struggled to keep control of the debate, frequently trying to keep President Donald Trump and former Vice President Joe Biden from interrupting each other.While Wallace at several points told Biden to allow Trump to speak, Wallace frequently told the president to stop interrupting, and at one point reminded Trump of the debate rules.“I hate to raise my voice but why should I be different than two of you,” Wallace said. “So here's the deal. We have six segments, we have ended that segment, we are going to go to the next segment. In that segment, you each will have two uninterrupted moments. In those two uninterrupted minutes, Mr. President, you can say anything you want.”During a question on replacing Justice Ruth Bader Ginsburg, Trump asked Biden if he would “pack” the Supreme Court."Will you shut up, man?" Biden responded.As Wallace attempted to move onto another topic, Biden said to Trump, “That was a productive segment, wasn't it? Keep yapping, man.”Trump responded, "The people understand, Joe. 47 years you've done nothing. They understand."Wallace was widely praised for his moderation of the 2016 debate between Clinton and Trump.While this was the first time Wallace has moderated a debate involving Biden, he had moderated a debate involving Trump four prior times.Wallace moderated three GOP debates for Fox News during the 2016 primary season. During one of the debates, Wallace chided Marco Rubio and Trump stating, “Gentlemen, you’re going to have to do better than this.” 1538

DENVER (AP) -- Wil Myers homered and Garrett Richards led a committee of pitchers that scattered seven hits as the San Diego Padres beat the Colorado Rockies 6-0 on Monday night.Even as San Diego capped a series of roster additions ahead of Monday's trade deadline, it was mostly holdovers providing the pitching and pop in the Padres' latest victory.Fernando Tatis Jr. hit a two-run triple, Eric Hosmer had an RBI double and Jurickson Profar delivered an RBI single among his three hits, helping the Padres take three of four in the series.It was San Diego's fifth shutout in Denver and first since April 12, 2017. 623

Democrat Dan McCready is withdrawing his concession in a North Carolina congressional race where investigators are probing allegations of election fraud.McCready got 905 fewer votes than Republican Mark Harris in the 9th District race. But the state elections board has refused to certify the results as it investigates potential misconduct with absentee ballots, making it the last undecided House contest in the country. The board could ultimately order another election.McCready had previously conceded the race to Harris, but withdrew that concession Thursday."I didn't serve overseas in the Marines to come home to NC and watch a criminal, bankrolled by my opponent, take away people's very right to vote," McCready tweeted. "Today I withdraw my concession and call on Mark Harris to end his silence and tell us exactly what he knew, and when."His reversal comes as the state elections board, as well as local and state prosecutors, investigate whether Leslie McCrae Dowless, a veteran operative in Bladen County who was hired by a consulting firm the Harris campaign paid 0,000, altered absentee ballots or collected them from voters but never turned them in.Dowless earned more than ,000 working on six campaigns dating back to 2010, and in most of those races, Dowless' candidates received a disproportionately higher percentage of absentee votes in Bladen County.Dowless has not returned CNN's requests for comment. He has denied any wrongdoing to The Charlotte Observer.Earlier Thursday, North Carolina Republican Party executive director Dallas Woodhouse told CNN he would support a new election if the elections board proves allegations of fraud are true and impacted the outcome of the race."We are not ready to call for a new election yet," Woodhouse said. "I think we have to let the board of elections come show their hand if they can show that this conceivably could have flipped the race in that neighborhood, we will absolutely support a new election."The-CNN-Wire 1997
